JC10M24R: KeyPair generation

Post by Diorin » Sat Sep 24, 2016 3:22 am

I have question about the new card JC10M24R .
There is an indication "KeyPair not supported" on the left of RSA512~2048. If it doesn't support KeyPair generation, how does it generate the key?
Thanks

If java card doesn't support KeyPair generation function,keys can be generated by outside card application and then transmitted to card.

In this case, the private key will be exposed. It's not a secure method.

We have already updated the JC10M24R card OS function. Now it can support RSA KeyPair Generation by default.

So you don't have to worry about this feature. Thanks!

Do you use flash memory/cards? I thought that javacards use ROM masks?

That really really nice! Why don't you sell the flash cards with SDK and without OS?
